An elegant means of self-protection in gram-negative bacteria by recognizing and extruding xenobiotics from the periplasmic space.

Abstract excerpt

Infection of Pseudomonas aeruginosa in cystic fibrosis patients is a major cause of mortality. This organism shows wide ranging antibiotic resistance that is largely attributable to the expression of xenobiotic efflux pump(s). Here, we show a novel mechanism by which the resistance-nodulation-division-type xenobiotic transporter expels potential hazards and protects the interior of the cells. The xenobiotic...
